I'm not currently looking for work, but I still want my résumé to look professional. I added this to it:

Currently, I'm working as a Child Development Engineer (a.k.a stay-at-home mom). My clients are 3 years old and second trimester gestation. I also do part-time contract programming work for various clients.

I wanted it to be a small playful/humorous blurb about my current employment situation. What do you think: Okay or not professional?
